According to sqouynd absorption lowering noise chute of the present utility model, by the sqouynd absorption lowering noise layer of being made by sound-absorbing material in the setting of chute outside, reach the object of sqouynd absorption lowering noise, can reduce noise emission, improvement work and living environment; Because the outside at sqouynd absorption lowering noise layer is also provided with screened housing; make material, the thickness of the sound-absorbing material that forms sqouynd absorption lowering noise layer have more selection, the sqouynd absorption lowering noise layer of particularly being made by ultra-fine centrifugally glass-wool has advantages of that acoustically effective is good, buying is convenient and cheap.
Accompanying drawing explanation
Fig. 1 shows the main TV structure figure according to the sqouynd absorption lowering noise chute of exemplary embodiment of the present utility model.
Fig. 2 shows the sectional structure chart intercepting along A-A line of the sqouynd absorption lowering noise chute in Fig. 1.
The specific embodiment
In order to reduce noise emission, improvement work and living environment, the utility model provides a kind of sqouynd absorption lowering noise chute, and described sqouynd absorption lowering noise chute comprises: chute housing; Be positioned at the abrasion-proof backing block of the inside of chute housing; Be positioned at the sqouynd absorption lowering noise layer of chute outside; Be positioned at the screened housing of sqouynd absorption lowering noise layer outside.
Describe below with reference to accompanying drawings the sqouynd absorption lowering noise chute of exemplary embodiment of the present utility model in detail.
Fig. 1 shows the main TV structure figure according to the sqouynd absorption lowering noise chute of exemplary embodiment of the present utility model.Fig. 2 shows the sectional structure chart intercepting along A-A line of the sqouynd absorption lowering noise chute in Fig. 1.
As depicted in figs. 1 and 2, according to sqouynd absorption lowering noise chute of the present utility model, in the inside of chute housing 1, be provided with abrasion-proof backing block 2.Chute housing 1 can be steel structure, and its profile can be square, circular or special-shaped etc.; Abrasion-proof backing block 2 can be polyethylene liner plate, and its thickness can be 20mm～40mm, is preferably 20mm.But, should be understood that, the utility model is not limited to this, chute housing 1 can be other structures except steel structure, abrasion-proof backing block 2 is also not limited to polyethylene liner plate, on the contrary, (character of for example material) selects material and the thickness of abrasion-proof backing block 2 and chute housing 1 according to actual needs.
According to the utility model; different from existing chute is; in the outer setting of chute housing 1, there are sqouynd absorption lowering noise layer 3 and the outside screened housing 4 that is arranged on sqouynd absorption lowering noise layer 3; this sqouynd absorption lowering noise layer 3 can fix on by being adhesively fixed on screened housing 4; screened housing 4 is welded on the outside of chute housing 1; therefore, sqouynd absorption lowering noise layer 3 is between chute housing 1 and screened housing 4.Sqouynd absorption lowering noise layer 3 can be made by the sound-absorbing material such as centrifugal super glass wool, also can be made by other sound-absorbing material; Sqouynd absorption lowering noise layer 3 can be fixed on chute housing 1 and/or screened housing 4 by the mode of gluing, bolt or rivet; The thickness of sqouynd absorption lowering noise layer 3 can be 25mm～100mm, can also determine as required the distance between chute housing 1 and screened housing 4; Screened housing 4 plays the effect of protection sqouynd absorption lowering noise layer 3, and its structure can be sheet steel, but is not limited to this.Chute housing 1 and screened housing 4 have formed double-deck steel structure; due to the protection of screened housing 4; make thickness and the material of sqouynd absorption lowering noise layer 3 have more selection; in the situation that space allows; can select the material that thickness is larger to make sqouynd absorption lowering noise layer 3, even can form sqouynd absorption lowering noise layer 3 by air.
The following examples are for describing the utility model in detail, and limit never in any form scope of the present utility model.
